本程序主要是对小车进行左转控制，有三种方法左轮抱死，右轮抱死，或者左轮后退右轮前进，三种方式进行左转(This procedure is mainly to control the car on the left, there are three ways, revolver, holding in death of the wheel lock, right or left back right wheel to go forward, three ways to turn left)

对于闭环控制有很好的说明以及pid算法的具体实现(Specific implementation for closed-loop control has a good explanation and pid algorithm)

模拟BMS，测试充电桩，经测试完好！符合《GB-T 27930-2015 电动汽车非车载传导式充电机与电池管理系统之间的通信协议》，用的USB转CAN外接模块。(Analog BMS, charging pile test, tested good! In line with the communication protocol between the GB-T 27930-2015-board electric vehicle conductive charging unit and battery management system. )

双两程电压表，用TLC1543做的，精准测电压(Double two-way voltmeter)

一个变压器保护的程序，是配电变电所内的保护程序(A transformer protection program, is within the power distribution substation protection program)

一个简单的open GL shader框架，简单到可以不用书籍就可以上手，(a simple openGL shader test, which is very simple enough make you to understand without any book)

单片机计算机设计，实现加减乘除，包括小数点的运算，用的是4*4的键盘(Single chip computer design, realization add, subtract, multiply and divide, including the operations of the decimal point, with 4* 4 is the keyboard)

可以产生幅度、频率可调的方波，频率50hz到1M(Can produce the amplitude, frequency adjustable Fang Bo, frequency of 50Hz to 1M)

这段代码包括了基于STM32对简单小车的循迹壁障以及L298N的驱动。并对其中关键部分进行了注释。(This code includes a simple car-based STM32 tracking barrier and L298N driver. And one of the key parts of the notes.)

用整数存储私有成员：年、月和日。为类提供构造函数，能够对各成员进行初始 化，但出现错误的初值时, 成员为2000-1-。也可以不在不提供任何初值的情况 下日期为2000-1-1。另外可以用一个Date 对象进行初始化，成员函数应实现以 下功能： （1） 对所有成员一次性赋值，也能对某个成员单独赋值，能够一次返回所有成 员的值，也能单独返回某个成员的值 （2） 可以按照mm-dd-yyyy 格式输出日期。 （3） 有成员函数nextDay（），用于将日期增加一天(Integer stored the private Members: year, month, and day. Class provides a constructor to initialize the members, but the wrong initial value, members 2000-1-. The date can also be not the case does not provide any initial value 2000-1-1. Also available on a Date object is initialized, the member function should achieve the following functions: (1) all members of the one-time assignment, can also be a member of a separate assignment, to return once the value of all the members, but also separate return a The members of the value (2) according to the date of mm-dd-yyyy format output. (3) member function nextDay () for additional day date)
